1. Self-aligning ball bearing has two rows of balls and a common concave sphered raceway in the outer ring. The bearing is consequently self-aligning and insensitive to angular misalignments of the shaft relative to the housing. It is particularly suitable for applications where considerable shaft deflections or misalignment are to be expected. Additionally, the self-aligning ball bearing has the lowest friction of all rolling bearings, which enables it to run cooler even at high speeds.

Compared with plain bearings, deep groove ball bearings of the excellent Compared with plain bearings, deep groove ball bearings of the inferior 1, the general conditions, the efficiency and fluid dynamic bearing lubrication bearing considerable, but higher than the number of hybrid bearings;  1, less able to withstand impact loading; 2, radial clearance is small, angular contact bearings can be used to preload cardiac

1, no backlash, high rigidityPreloading ball screw can be added, as pre-clearance to negative axial pressure can then be more rigid.2, high-precision guaranteeBall screw by a high level of consistent production out of machinery and equipment to produce higher accuracy.3, micro-feed mayAs the ball screw is the use of ball movement, so a very small starting torque, does not appear as a creeping phenomenon of sliding movement can ensure accurate micro-feed.

There is also suitable for high-speed rotation of synthetic resin molded cage)2. Analysis of Lubrication (used for high-speed spin cycle lubrication, spray lubrication, oil mist lubrication and oil lubrication Lubrication)3. Of bearing internal clearance (taking into account the bearing temperature rise generated internal clearance reduction)
